Null will never disappear off the Internet. Eating whole blocks of cheese in one sitting and spending 20 hours a day banning people on his website for disagreeing with him are the only things Josh has going for them. Josh has no IRL friends (or Internet friends outside of simps and clout chasers), no hobbies, no family, no romantic partners, no working dick, and only leaves his computer chair to scooter his way to the door and pick up his doordash delivery of ultra processed canned vegetables and cheese pallets.
I don't think he'll kill himself, but rather he'll barnacle himself to the Internet and jump from grift to grift like EDP445 or Ethan Ralph, leeching off of an ever shrinking audience for attention and donos.
